Hi to all PICListers! Have you used Electronics Workbench(EW)? If you have then probably you'd wish a PIC simulator works like that. This is where you can design both the project circuit diagram,edit source code and simulate it at the same time. At the end of a successful simulation, a netlist file, with format option, will be produced for PCB artwork and the intergrated programmer will blast a chosen PIC. Features: External interrupts can be triggered using any assigned key(s) or button(s) on the keyboard, which is also definable as nXm keypad. Word generator or any clock source can also be used. The outputs then can be used to drive virtual LED's, 7X, LCD (graphic dot matrix type is very exciting!), buzzers, relays, logic analyzer, oscilloscope, etc. It can also handle multiple and different PIC devices in one design! Just point, click and drag the components on the tools bar into the workspace and wire them up. Double click on any PIC chip icon on the circuit diagram will execute source code editor and assembler for that PIC with options like choosing PIC type, clock, fuses etc. Then you're ready to go! This is quite easy, both encouraging and time saving for beginners and experts alike without the hassles of stimulus file or any other stuffs that you are NOT dealing with in the real world! The best thing is you don't even have to go near to the real thing! You can forget about the real emulator. Multiple WATCH as in MPLab-SIM is good. It monitors the activities of all chosen registers. MP-Driveway and UMPS are good but lack of circuit diagram design facility like VICE. They have a lot of unneccessary files, resources etc. that you don't have to know about as in the real world. And they are not straight forward and not as easy to use as VICE. Especially if you're just spending half an hour or so evaluating it. BUT hey folks! Don't be so excited yet! It's just my wish to have this sort of software. I think it's not a bad idea for Interactive Image Technologies (the maker of Electronic Workbench) and Microchip to work together on this idea. Perhaps I'll make a suggestion to both. NOT neccessarily these two companies. Any other third parties why not? Let me know the exciting news i.e ready for market. What do you all PICListers think about that? Thank you Sam Malaysia
